If you have website that you are growing, you will soon realize that there will be spikes in server requests. If you do not have the right technology provided by a web host, the results can be slow loading times or even go temporarily offline. For an ecommerce site, this can have a tremendous negative impact as the results can be loss of customers and loss of sales. If your website is experience such problems you may require an upgrade to multiple server. In such a situation, you should consider the benefits of load balancing.
The term Load balancing means a method of distributing a server’s work load across multiple servers. More than one machine can be connected to make it seem like one virtual server or machines arranged in clusters. Within this technology, there is a router or hardware switch that directs requests among them to reduce load times. Therefore, load balancing is attained by both software or hardware based executions. With Software-based load balancing, the software needs to be installed on the servers in a load-balanced cluster. Hardware-based load balancing makes use of a router or switch that has load balancing software installed on it.
Load Balanced Server Advantages
Better Scalability: Processing power can be better utilized when load balancing is configured on a server. Requests can be directed to the processors that have the lowest demand which make response time much quicker. As well, there is the ability to prioritize applications so that user interactions are handled with the highest priority. Some servers may be taken offline when demand is low and then brought back online when needed.
Improved Performance: Multiple processors can manage a single user request with faster download times for the end user. In addition, with load balancing, an online shopper with a full cart is able to split their load and move through more than one channel to clear the bottleneck much faster.
High Availability: Load balancing over multiple servers gives one the ability to be taken offline for maintenance and also offers a level of disaster recovery. In the event of a single server or complete site failure, provisions can be made for alternate routing.
Cloud Computing and Load Balancing
When it comes to cloud computing, load balancing is important. The load balancer allows for the ability to assess and monitor demand which is essential as cloud computing permits dynamic scaling of resources on demand. If you have website that you are growing, load balancing can effectively handle the spikes in server requests.
